Netflix is making its first foray into reality competition with a new series from Sylvester Stallone. Ultimate Beastmaster will pit competitors from six countries against each other in a brutal obstacle course, culminating in one overall series winner.

The show will run for 10 hour-long episodes that send competitors from the U.S., Brazil, South Korea, Mexico, Germany, and Japan into “The Beast” obstacle course to crown a different “Beastmaster.” Each episode will feature 12 competitors — two from each participating country — and the finale will send the nine “Beastmasters” crowned in the previous episodes into one final obstacle course to compete for the title of “Ultimate Beastmaster.”

Ultimate Beastmaster will also be a new step for Netflix in another aspect — it will be broadcast in six customized local versions depending on the country where the viewer is watching. In each country, the show will have a different set of hosts, be broadcast in the native language, and focus on the competitors from that country. The hosts for each country are as follows:

The series comes from producers Sylvester Stallone and The Biggest Loser executive producer David Broome.

“The world will watch in awe as amazing competitors from around the globe overcome grueling physical challenges — and in the process become champions and heroes,” Stallone said in a statement. “The course is unequaled in its daring creation and I am excited to be a part of it.”
